The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art. The embodiments described below and the features of the embodiments can be combined with each other without conflict.

In some technologies, the winding manner of the coil panel is as follows: most be the center around the wire reel according to following the pointer or anticlockwise from interior to exterior or from exterior to interior coiling in proper order and form, so set up for the magnetic field opposite direction (current opposite direction promptly) that the both sides wire at coil panel center formed, the central magnetic field of coil panel is offset each other, and then makes the central heating blind area appear in the coil panel. Or, the coil panel sets up the wire reel when the wire winding, because the central zone of wire reel can't wind, leads to the central heating blind area to appear in the coil panel.

The embodiment provides a coil panel and electromagnetic heating cooking utensil, through set up first wire reel and second wire reel on coil panel seat 100 to make the wire winding direction of wire in first wire reel opposite with the wire winding direction of second wire reel, alleviated the problem that the central zone of the coil panel that exists has the central heating blind area among the correlation technique, reached the effect of eliminating the central heating blind area of coil panel.

The technical scheme in this embodiment for solving the central zone of above-mentioned coil panel and having the technical problem of central heating blind area, the general thinking is as follows:

a first wire spool and a second wire spool are arranged on the disk surface (namely the front disk surface) of the coil disk seat 100, wherein the first wire spool and the second wire spool are both arranged into a plurality of coils from inside to outside; the tail end (namely the wire outlet) of the first wire spool is communicated with the head end (the wire inlet) of the second wire spool, so that the wire can be led into the second wire spool for winding, wherein when the wire is wound in the first wire spool and the second wire spool, the winding direction of the wire in the first wire spool is opposite to the winding direction of the second wire spool.

It should be noted that the "winding direction" mentioned in this embodiment refers to a clockwise winding direction and a counterclockwise winding direction. Through the winding mode of the embodiment, the winding direction of the wire in the area adjacent to the first winding disc and the second winding disc is consistent, namely the current direction is consistent, so that the magnetic field is enhanced.

For convenience of description, a region of the wire adjacent to the first wire spool and the second wire spool is referred to as a wire winding same-direction region.

Specifically, when the winding direction of the wire in the first spool is a counterclockwise winding direction and the winding direction in the second spool is a clockwise winding direction, the current direction of the wire in the winding equidirectional region is the same (see fig. 4 in particular).

Through the arrangement, when the center of the coil base 100 is covered by the winding equidirectional region, the magnetic density of the central region of the coil base 100 can be enhanced, so that the central heating blind area of the coil panel is eliminated, the thermal power density of a pot or a kettle at the center is increased, and through the winding mode of the embodiment, the whole coil base 100 can be wound around most of the panel surface region of the central region, so that the coil panel can be uniformly heated.

It should be noted that, the winding equidirectional region is arranged in the central region of the winding disc as corresponding as possible, so that the central heating blind zone of the coil disc can be eliminated better.

In order to better understand the technical solution, the technical solution will be described in detail with reference to the drawings and the specific embodiments.

The wire spool provided by the embodiment can be applied to electric products such as an induction cooker, an electric pressure cooker, an electric chafing dish, an electric kettle and the like, and achieves the purpose of electromagnetically heating corresponding pots or kettles; wherein, the central heating blind area of coil panel can be eliminated to the coil panel of this embodiment, further realizes the even heating for the coil panel and provides probably.

The structure of the coil bobbin 100 will be described in detail with reference to the accompanying drawings.

Referring to fig. 1, the coil tray 100 includes a tray bottom, an edge of the tray bottom extends to the front tray surface side along the axial direction to form a baffle ring, and a space for arranging the wire spool is enclosed between the circular tray bottom and the baffle ring; the area of the wire spool is smaller than the area of the bottom surface of the tray bottom, and the wire spool covers most of the area of the bottom surface of the tray bottom, so that the heating uniformity is improved.

With continued reference to fig. 1, the outer wall surface of the coil disc seat 100 is provided with a mounting seat extending radially outwards, and the mounting seat is provided with a connecting hole for mounting the coil disc seat on an electrical product.

Specifically, the mounting seat may be a circular thin plate, a threaded hole is formed in the mounting seat, a central line of the screw hole is parallel to an axis of the coil disc seat 100, and the screw penetrates through the threaded hole and a corresponding hole in the electrical product, so that the coil disc seat 100 can be fixedly mounted on the electrical product.

Alternatively, the circular thin plate may be welded to the outer wall surface of the coil bobbin 100.

In order to improve the stability of the installation of the coil disk holder 100, the installation holder may be provided in plurality, for example, two, three, four, or more.

In this embodiment, the number of the mounting seats is three, and an angle between two adjacent mounting seats is 120 degrees.

As a variation, the coil base 100 may be mounted on the electrical product by means of clamping, inserting, or bonding.

In consideration of actual use requirements of different electrical products, the coil base 100 may be configured as a circular base, a rectangular base, a special-shaped base, or the like; the rectangular disk seat can be a square disk seat or a rectangular disk seat.

The coil base 100 in this embodiment is a circular base, and correspondingly, the base is a circular base, the baffle ring is a circular baffle ring, and the other shape of the coil base refers to the circular base, which is not described herein again.

Fig. 1 shows a structure form that a wire spool is arranged on a circular disk seat. In any form of the coil base 100, the structure of the wire spool on the coil base 100 is substantially the same, and specifically, the shape, size, number of turns, and the like may be modified appropriately, so that wire spools with different structural forms of different coil bases 100 may be obtained.

The structure of the coil winding plate will be described in detail with reference to the accompanying drawings.

Referring to fig. 1, the wire reels on the coil bobbin base 100 are arranged in a group, and the group of wire reels includes a first wire reel and a second wire reel; structurally, the first wire spool and the second wire spool are arranged into a plurality of turns from inside to outside, for example, three turns, four turns, five turns, six turns, seven turns and more; of course, the specific number of turns of the first and second wire spools may be selected according to the number of wire spools, the interval between adjacent turns, the size of the wire spool (or the area of the face of the coil block 100), and the like.

In short, when the wire reels are arranged as a group, the number of turns of the first wire reel and the second wire reel can be properly increased, and meanwhile, the interval between the adjacent turns is reduced (so as to increase the number of wound wires); when the wire reels are arranged in multiple groups, the number of turns of the first wire reel and the second wire reel can be properly reduced, and simultaneously, the interval between adjacent turns is reduced (or increased) (so as to increase the number of wound wires) to arrange the wire reels with proper number on the limited area of the disc surface.

For example, for an induction cooker used in a general kitchen, the wire reels may be arranged in a group (i.e., a first wire reel and a second wire reel are arranged); the first wire spool and the second wire spool are arranged into seven circles, and the interval between adjacent circles is 1 mm; the area where the first winding reel or the second winding slot is disposed covers most of the disc surface area of the coil disc holder 100.

In other embodiments, the winding disks on the coil base 100 are arranged in multiple groups, and referring to fig. 1, in such a structure, the coverage area of one group of winding disks can be reduced appropriately, and meanwhile, multiple groups of winding disks, for example, two, three, four, or more groups of winding disks, are arranged on the coil base 100. When the wire reels are provided in plural sets, one of the wire reels may be provided in a central region of the wire reels in order to ensure that a central heating blind area of the wire reels can be eliminated.

Referring to fig. 1, the first wire spool and the second wire spool are arranged in a central symmetry manner, so that the wires can be uniformly wound, the wires uniformly cover the disk surface of the coil disk seat 100, and the purpose of uniform heating is further achieved.

Further, since the wire spool has a symmetrical center, the symmetrical center is disposed at the center of the coil base 100, so that a central heating blind area of the coil disk can be better eliminated, and the coil disk can be uniformly heated.

As a modification, the symmetrical center of the coil bobbin may be slightly deviated from the center of the coil base 100, and thus, since the symmetrical center of the coil bobbin is uniformly wound in all regions, the function of enhancing the magnetic density can be achieved in a certain region, and even if the symmetrical center of the coil bobbin is slightly deviated from the center of the coil base 100, the dead zone of the center heating of the coil bobbin can be relatively eliminated.

In this embodiment, the specific structure of the wire spool may take the following form.

(1) First form of wire spool

Referring to fig. 1, each of the first and second wire reels includes a plurality of turns of slot walls protruding from a front surface of the coil base 100, and the plurality of turns of slot walls are sequentially increased from inside to outside so as to form a wire slot between two adjacent turns of slot walls.

Furthermore, the corresponding positions of the multi-ring groove walls on the respective ring structure are provided with fractures, so that the winding grooves of the inner ring can be communicated with the winding grooves of the outer ring, staggered communication (namely staggered continuous winding) between the adjacent winding grooves is realized, and continuous winding of the wire is further realized.

For convenience of differentiation and description, referring to fig. 2 and 3, a slot wall corresponding to the first wire spool is a first slot wall 211, and a corresponding fracture is a first fracture 2111; the slot wall corresponding to the second wire spool is the second slot wall 221, and the corresponding fracture is the second fracture 2211.

Specifically, the heights of the first slot wall 211 and the second slot wall 221 may not be limited to meet the winding requirement. The first groove wall 211 and the second groove wall 221 have a thickness ranging from 1 to 1.5mm, and may have a thickness of 1mm, 1.1mm, 1.2mm, 1.3mm, 1.4mm, or 1.5mm, for example.

With continued reference to fig. 2, the above-mentioned "break" may be understood as a break formed by forming a long hole 300 in the winding equidirectional region, wherein the long hole 300 can sequentially break the winding slot of the first winding reel and the winding slot of the second winding reel.

Alternatively, the hole diameter of the long hole 300 is uniform at all positions. The extending direction of the long hole 300 may be a connecting direction of the winding centers of the first and second wire reels.

Referring to fig. 2 again, in this structure, each winding slot is at the break, the notches at both sides are arranged oppositely, and during continuous winding, it is necessary to wind from the notch of the inner circle to the notch of the outer circle or from the notch of the outer circle to the notch of the inner circle; in this form, in addition to satisfying the dislocation communication of each winding groove in the first wire spool, when being introduced to the second wire spool from the first wire spool, the tail end of the first wire spool (i.e., the outermost winding outlet) and the head end of the second wire spool (i.e., the outermost winding inlet) also need to be communicated.

In this embodiment, the first wire spool and the second wire spool are both waist-shaped structures, and the groove side wall of one side of the waist-shaped structure, which is far away from the wire winding equidirectional region, is an outward-convex arc groove wall.

With such an arrangement, the winding density of the wire in the winding homodromous area is greater than that in other areas except the winding homodromous area of the coil base, so that the magnetic density of the winding homodromous area of the coil base 100 is further enhanced, and the heating effect of the central area is improved.

It should be noted that the "other regions" mentioned above may be understood as regions located on the left and right sides of the region in which the winding lines are in the same direction.

In other embodiments, the winding grooves of the first winding disc and the winding grooves of the second winding disc may also be circular grooves with a fracture, oblong grooves or other special-shaped grooves, and of course, other types of grooves satisfying the aforementioned winding manner are within the protection scope of the present invention.

(2) Second form of spool

The second form of the spool differs from the first form in that: the winding groove of the first winding disc and the winding groove of the second winding disc are continuous double-spiral grooves.

Specifically, the first wire spool is shaped like a mosquito coil, and the outlet of the inner circle is also the inlet of the outer circle adjacent to the inner circle; the second wire winding disc is also in a shape similar to a mosquito coil, and the outlet of the inner circle is also the inlet of the outer circle adjacent to the inner circle; and the export of the outermost round of first wire reel and the entry dislocation connection of the opposite direction setting of the outermost round of second wire reel, the tail end of first wire reel and the head end dislocation connection of second wire reel promptly.

The above-mentioned "staggered connection" means that the notches of the adjacent winding slots are staggered and connected at the fracture to form a continuous winding slot.

In brief, the wire spool is a continuous double spiral groove, which has a wire inlet for leading the wire to penetrate into the innermost ring of the first wire spool and a wire outlet for leading the wire out of the innermost ring of the second wire spool, and the other part is a continuous spiral wire spool groove for connecting the wire inlet and the wire outlet.

The wire is wound in the wire spool, so that the winding position of the wire can be effectively controlled, the wire is prevented from deviating, and uniform winding is ensured. The wire spool can be reasonably arranged according to the winding mode (or winding track) of the lead when the wire spool is arranged.

According to the above-described wire spool, the following two winding methods are specifically possible. The following description is made with reference to the accompanying drawings.

In this embodiment, the lead may be led from the first wire spool to the second wire spool and continuously wound, and may also be led from the second wire spool to the first wire spool and continuously wound.

Specifically, one winding method of the wire in this embodiment is as follows: referring to fig. 1, after the wire is wound around the wire winding groove of the first wire winding disc from inside to outside counterclockwise, the wire is led into the second wire winding disc, and is wound around the wire winding groove of the second wire winding disc from outside to inside clockwise.

Specifically, referring to fig. 2, the wire is firstly wound from the inner ring to the outer ring in a counterclockwise manner on the first wire spool (the route is 11-12-13-14-15-16-17); then introduced to the second spool in a clockwise direction (path 17-21-22-23-24-25-26-27).

The winding slot at the position 11 is the head end of the first winding disc, and the winding slot at the position 17 is the tail end of the first winding disc; the winding slot at the position 21 is the head end of the second winding disc, and the winding slot at the position 27 is the tail end of the second winding disc. The first and second spools make a transition (or turn) at the spool slots at locations 17 and 21.

It should be noted that, in this embodiment, seven turns of the winding groove are taken as an example, and needless to say, when the winding groove is set to other turns, the specific winding manner may refer to seven turns, which is not described in detail herein.

Another winding method of the wire in this embodiment is (not shown in the drawings): the wire is clockwise around establishing the back at the wire winding groove of first wire reel from inside to outside, is introduced the second wire reel to counter-clockwise around establishing at the wire winding groove of second wire reel from outside to inside.

In summary, the wire spool in the present embodiment can realize continuous winding of the wire; the wire can be a single wire, and the single wire is formed by one or more turns of wire filaments, namely, the single-coil winding groove can simultaneously accommodate the multiple turns of wire filaments, and the multiple turns of wire filaments can be twisted together and then wound; or, the single wire is wound in a flat spreading mode; as a variant, the individual conductors can also be arranged in a plurality of layers, i.e. the individual conductors are wound in a plurality of layers upwards in the radial direction, in which structural form the width of the winding groove can accommodate the individual conductors, while the depth of the winding groove can accommodate the plurality of layers of conductors simultaneously.

Wherein the multi-turn wire may range from 2-5 turns; illustratively, there may be 2 turns, 3 turns, 4 turns, or 5 turns.

As a variation, the wire spool of the present embodiment is also suitable for connecting a plurality of wires, and winding the wires along the same path as a single wire.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; while the utility model has been described in detail and with reference to the foregoing embodiments, it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; and the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the scope of the technical solutions of the embodiments of the present invention.
